This is what I’m using. it’s not working. why not?

```auto

if (firstName != "" || lastName != "" || address1 != "" || city != "" || state != "" || zip != "" || emalAddress != "" || phone != ""){
	trace(fieldClip.firstName +" "+fieldClip.lastName +" "+fieldClip.address1+" "+fieldClip.address2+" "+fieldClip.city+" "+fieldClip.state+" "+fieldClip.zip+" "+fieldClip.emailAddress+" "+fieldClip.phone);
	this.gotoAndStop("step2");
}else{
	
	this.gotoAndPlay("error");
}

```
